LATHER-FOBMING DEVICE.

Application tiled July 29, 1922. Serial No. 578,401.

To all `whom if 4may concern.

Be it known that: I. ROBERT HUDSON IVAGEP., a citizen of the UnitedStates, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in aLather-Forming Device; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in devices for forming lather forshaving purposes and has reference more particularly to a device inwhich air is injected into a chamber containing a saponaceous liquid,the suds being then forced through means for breaking the bubbles andcondensing their soap content into a smooth lather,

prior todischarge for use. A device of this character is shown by mypending U. S. application, Serial No. 544,059. filed Mar. 15, 1922, butthe present invention aims to provide improved means for condensing thesoap content of the generated bubbles, as well as to provide an improvedarrangement, whereby the bubbles or suds will be effectively genera-ted,regardless of the size to which the cake of coap has worn.` The methodor process described herein, is claimed in my co-pending applicationSerial To. 699,133 filed March 13, 1924 which is a division ofapplication Serial No. 544,059.

With the foregoing in view, the invention resides in the novel subjectmatter hereinafter described and claimed, the description beingsupplemented by the accompanying drawings.

Figure` 14 is a view similar to the upper portion of Figure 4 butillustrating a slightly different form of construction.

In the drawings above briefly described,l

lwith ribs 4to hold the soap cake against rotation thereon. The platform3 is spaced above the bottom of the receptacle 1 and I provide means forsupplying air under pressure to the Space beneath said platform, so thatair will be supplied to the water around the edge of als the platform 3and soap cake :2 thereon.

In the preferred form of construction, the lower side of the platform 3is provided with a centrally disposed'depending neck 5 threaded-into'the enlarged upper end of an air supply passage 6 which is formed in thebott-om portion of the receptacle. The neck 5 is formed with a passage 7communicating with the delivery end of the passage 6 and a plurality ofair discharge ports 8 lead `from said passage/7 through the neck tosupply air in radial jets beneath the soap supporting platform 3. In thepreferred from of construction. 'the lower side of this platform isprovided wit-h a plurality of curved substantially radial ribs 9 locatedbetween the ports 8 and defining passages of such shape and to impart awhirling motion to the water within theyreceptacle 1, when air underpressure is yforced into the device through the passage Ywhich passentirely through the platform 3. Thus, by the time the soap `cake hasworn down to such an extent as to revent the ei'ective formation of soapbub les byl whirling of the water around the cake, jets of air and waterWill be forced upwardly through the ports 11 against the Vcake whichthen assumes substantially the shape shown by the dotted lines in Fig.

2. Thus, the soap cake can be entirely used and no waste willthereforeccur.

The meeting portions, of the passages 6 and 7 are flared to form a valvecage and with a dependin seat within which a ball check 12 is located soas to prevent .any liquid from running into the passage 6 fromthe'receptacle 1, while permitting air under pressure from the bulb 10tovpassfreely into said receptacle. To pre vent upward closing y of thecheck 12, any suitable provision may be made, such as forming grooves 13in the wall of the pas-pl sage 7 at its flared lower end.`

For the purpose of filling thereceptacle 1 with water, I provide it witha suitable lilling neck 14 having a` removable closure 15 which ispreferably heldin place by means of a pin .16- and bayonet slots 17, anappropriate gasket 18 being interposed between the closure and the neckto form a liquid tight connection. Attention ma lhere be directed to thefact that the nec 14 constitutes an overiow for the receptacle 1,preventing filling of the latter to an undesirable extent. The locationof this neck insures that suiicient water shall not be supplied to thereceptacle 1, to run from either'the upper or lower end of the latter,should it be accidentally tilted or laid upon one side. This is due tothe fact that the level of`liquid in the receptacle will not reachas'high as the passage 7 or the central outlet from the upper end of thereceptacle 1, if the latter is ina position at an angle or on one side.

The numeral 20 designates a removable cap threaded upon the upper end ofthe receptacle 1 and provided with a lather outlet spout 21. This capcontains final suds condensing means and preliminary condensingmeans arelocated within-a hollow partitlon which separates the receptacle fromthe ca In the present showing, a disk 22A is c amped between thereceptacle and the cap 20, said disk being provided annular ange 23closed at its lower en by a disk 24 which is ybein riphery. The edge ofAthis disk as here shown, is provided with an upwardly ex- ,l

tending rib 26 upon which a screen 27 rests. A second disk 28 rests uponthe screen 27 and is provided with a central aperture 29. A secondscreen 30 rests upon the upper side of the disk 28 and is held againstthe same by a spacing ring 31 bearing against the upper side of saidscreen 30. Between the ring 31 and the late 22, a third screen 32 ispositioned, w ich screen extends across the central outlet opening 33with which the plate 22 is formed. A spring ring 34 is preferablyprovided to hold the several parts 24-32 within the flange `23 and itwill be seen that removal of this spring ring, will permit easydisassembly of the initial -suds condensing means for cleaning purposes.The ring 31 and disk 28 serve as spacing members between the adjacentscreens.

The capy 20 is provided with a central depending sleeve 35 whichregisters at its lower .end with the opening 33, said sleeve formed withan outlet opening 36 placing it in communication with the space betweensaid sleeve and the peripheral wall of the cap. Extending across thisspace between the openin 36 an the spout 21, is a partition 37 w ichforces the suds discharged through the opening 36, to travel entirelyaround the interior of the cap before it is. discharged through thespout ,21. During this travel, a number of screens 38 are encounteredand these screens act to further condense the soap content of thepartially condensed suds, so that a thick smooth lather 'fs produced forexpulsion through the spout 21.

As shown most clearly in Figuresr 6, 7, 11 and 12, each screen 38 ispreferably mounted on a rigid sheet metal frame 39 andthe cap isprovidedwith vertical guide formed withy grooves 41 receiving the upperportions of said frames.A

Tooperate the device, a cake of soap is pressed downwardly upon theplatform 3 and the plate 22 with its condensing means and the cap 20,are again secured in place. The closure 15 is now removed and thereceptacle 1 isl filled with water to the extent permitted by the neck14. When this closure Ais again aplied, the device is in readiness'foruse.` peration of the bulb or'the like'lO will now cause discharge ofair under pressure into the receptacle- 1 around the cake 2,therebyforming soap bubbles which are forced out through the openings25, 29 and 33, and the interposed screens, Thus, the .soap bubbles` arebroken up and their soap content isreduced t0 a lather which isdischarged through the opening 36 and must pass through the screens 3Sbefore reaching the discharge spout 21, the result being thatl furthercondensation takes place and when the lather is finally discharged, itvis in the form of a thick smooth cream of proper consistency forshaving. rllhis lather may be caught in the hand and applied to the facedirectly. sothat the use ot' an unsanitary brush is not necessary.

' l have found in actual practice, that the soap suds in being pressedby the action of the bulb. through the several extremely tine screenswithin the ange. 23 will pulsate them and permeate between these screensand the adjacent disks and will ooze through the entire areas of saidscreens instead of only through the portions extendingover the severalopenings. Thus. a. thorough breaking up of the soap suds is producedwhich insures a perfect lather.

In view of the tact that excellent results are being wbtaincl 'from theexact details shown and described. these details may well be followed.but it is to be understood that within the scope of the invention asclaimed, numerous minor changes may be made. It

will be understood that any suitable pro-Vy vision may be madefor'providingan air tight or liquid tight jointl wherever desired. Thenumerals l5 in Figures 2. l and 1st, designate suitable ground jointsfor this purpose.
